Kurze Antwort
Two KEY items turn up in the Day 2 footage: the Maintenance Key Ring and a red Emergency Cupboard Key. The player had the key ring when the toolbox read "Inside the latched toolbox", and the Emergency Cupboard Key when the latch clicked open. A separate door reads "A steel-faced cupboard door with a first-aid cross - locked", with a loud "Force the door" option (hold G). We didn't see the cupboard key open it.

What the cards and prompts say
| Item or door | Text |
|---|---|
| Maintenance Key Ring | Card tagged KEY |
| Emergency Cupboard Key | Card tagged KEY (a red key) |
| Toolbox | "Inside the latched toolbox", then "The latch clicks open - pliers, a wrench and a tag inside" |
| Cupboard door | "A steel-faced cupboard door with a first-aid cross - locked" |
| Force option | "Force the door (loud) (hold)" on G |
Which key opens what
The toolbox is the one we can tie to a key: the latch opened while the Emergency Cupboard Key was selected, after the Maintenance Key Ring had been held at 02:50. The footage doesn't show a lock animation, so we can't say for sure which key did it.
The name suggests the red Emergency Cupboard Key belongs to the steel cupboard marked with a first-aid cross. The video shows that cupboard locked, with the loud force option, but never unlocked. We don't list a result for it.
Forcing a door is loud
The prompt labels forcing the cupboard door as "loud", and the Day 12 objective warns the same about the jammed east fire door. Zombies come to noise, so clear the corridor first.
Tips
- Check the toolbox on Day 2: it holds the wrench you need for the riser valve on Day 5.
- Use the key before you force a door; forcing is loud.
- Keep the Hammer in hand if you plan to force the cupboard, as in the footage.
